Reach Resources Limited (ASX: RR1 & RR1O) (“Reach” or “the Company”) is pleased to advise that a recent review of airborne, magnetic, and radiometric geophysical data by Southern Geoscience has identified a large ovoid intrusive feature, at the Company’s 100% owned Wabli Creek Project, WA.
HIGHLIGHTS
- A review of available geophysical data by Southern Geoscience on the Company’s 100% owned, Wabli Creek Project, Yinnetharra WA, has identified a large ovoid intrusive feature/magnetic target (Figure 1).
- The magnetic anomaly has been interpreted as a late-stage intrusive granitic sequence, internal to the regionally extensive Durlacher Supersuite, and proximal to the Chalba Shear Zone.
- The 3 highest priority existing geochemical targets, including an area where historical high- grade niobium eluvial mining has been undertaken, have been confirmed to be associated with structures located at the margin of the newly identified magnetic intrusive feature.
- This is the first time that such a potential link has been indicated at Wabli Creek and if correct, it expands the potential of the project to host significant Nb-Y-REE mineralisation.
- Including new targets, a total of 27 targets have now been identified which will be the focus for ongoing exploration.
- High grade eluvial results previously reported include:
- Niobium:
- 32% Nb2O5 (ASX Announcement 1 June & 13 December 2022)
- 14.3% Nb2O5 (ASX Announcement 1 June & 21 December 2023)
- Yttrium:
- 0.72% Y2O3 (ASX Announcement 13 December 2022)
- Rare Earth Elements:
- 2.6% TREO (ASX Announcement 13 December 2022)
- Niobium:
- Following the successful review by Southern Geoscience, detailed airborne geophysical surveys including magnetics, radiometrics and gravity are now planned to further refine priority targets, and potentially identify further additional targets.
The large intrusive feature is coincident with previously reported high grade Nb-Y-REE results from eluvial samples and high priority soil geochemical anomalies.

Located in the highly prospective Gascoyne “Battery Metals” Province of Western Australia, approximately 150kms north of Gascoyne Junction, the Wabli Creek project has provided high grade niobium and TREO results up to 32% Nb2O5, 14.3% Nb2O5 and 2.6% TREO. (ASX Announcement 13 Dec 2022, 1 June 2023).
The newly identified ovoid magnetic feature is interpreted to be a younger granitic sequence which has intruded into the older, regionally extensive, Durlacher Supersuite, proximal to the Chalba Shear Zone, a major E-W trending structural corridor.
Importantly, the existing 3 highest priority geochemical anomalies, together with the area historically mined for high-grade niobium eluvium all occur along the margins of this newly identified feature, suggesting a potential genetic link between the intrusive and known mineralisation.
This is the first time that such a potential link has been indicated at Wabli Creek and if correct, it expands the potential of the project to host significant Nb-Y-REE mineralisation.
Geophysical Surveys
Southern Geoscience completed a review of all available geophysical data over the Wabli Creek Project area, with the aim of producing a structural interpretation based on public domain airborne magnetic data, radiometric data and satellite imagery. The key outcome following the study was the identification of a large “ovoid-shaped” magnetic feature central to E09/2377(Refer to Figures 1 and 2).
Importantly, a total of 27 targets have now been identified and will be the focus for ongoing exploration at Wabli Creek, for Niobium-Yttrium-Rare Earth Elements.
Given the success of the geophysical review, and the relatively low resolution of the existing magnetic and radiometric surveys at Wabli Creek (~400m line spacing, 80m station spacing), detailed airborne geophysical surveys including magnetics, radiometrics and gravity are now planned to further refine priority targets and to potentially identify additional exploration targets.
Jeremy Bower CEO commented:
“The identification of a potentially late stage, younger, granitic intrusive sequence at Wabli Creek is really exciting.
We have previously reported some very high grade Nb-Y-REE rock chip and soil results at Wabli Creek, and having now located what may be the source of mineralisation, could potentially be of significant importance in understanding the source of the mineralization at the project.”

Outcropping Copper Gossan Delivers 33% Cu Assays At Morrissey Hill Project, Yinnetharra
HIGHLIGHTS
- High grade copper‐oxide mineralisation (malachite) confirmed at the Company’s Morrissey Hill Project, Yinnetharra with rock chip samples reporting highly encouraging assays of up to 33.2% Cu; 0.2 g/t Au and 141.8g/t Ag. (Figure 1).
- Results follow Morrissey Hill assays of up to 2.3% Li2O (ASX Announcement 15 May 2023).
- Mineralisation at the Swallowtail Copper Prospect was mapped over a strike length of at least 150m and remains open in all directions.
- Significant results include:
- 33.2% Cu, 0.2g/t Au and 141.8g/t Ag (23RRRK0039).
- 14.7% Cu, 0.02g/t Au and 55.6g/t Ag (23RRRK0042).
- 4.2% Cu, 0.3g/t Au and 5.7g/t Ag (23RRRK0041).
- 2.3% Cu, 0. 2g/t Au and 5.0g/t Ag (23RRRK0043).
- Historical sampling 3.0km’s west of Swallowtail could potentially extend the strike with historical results returned:
- 18.5% Cu, 1.1g/t Au and 6.8g/t Ag
- 18.5% Cu, 1.1g/t Au and 6.8g/t Ag
- The rock chip results confirm the Company’s targeting methodology and the potential of the area to host significant mineralisation.
- Morrissey has never been drilled & geochemical surveys planned to commence next week.
Commenting on the results CEO Jeremy Bower said:
“The Morrissey Hill tenement at our Yinnetharra Project continues to deliver. These are outstanding copper results and in conjunction with the 2.3% Li20 announced earlier this week, it is clear how prospective the ground is. We’re focused on sourcing the critical and battery minerals of the future and copper is an important part of our strategy. Despite several world class copper‐gold and polymetallic base metal deposits in the East Capricorn Orogen, the West Capricorn and Gascoyne has been massively under‐ explored. We see this as a huge opportunity.
Importantly, we are fully funded to complete our field programs and drilling campaigns earmarked for this year. Our focus remains on thorough geochemical assessment of each target and getting drill rigs out to Morrissey Hill as soon as possible. This will mean consistent news flow for our shareholders over the coming months.”

The rock chip results confirm the Company’s targeting methodology and the potential of the area to host significant mineralisation. Systematic surface geochemical surveys including soils, stream sediment and rock chip sampling are planned to commence immediately. Results from this work will guide follow up programs which if warranted may include electromagnetic geophysical surveys and drill testing of priority targets.
The results were reported from an outcropping quartz‐veined gossan, the Swallowtail Prospect, showing visible malachite (copper‐oxide) over a strike length of approximately 150m. The gossan strikes east‐ west, appears to dip steeply towards the south and remains open in both directions. A single historical sample located some 3.0km’s west of Swallowtail, and within the same structural corridor, also reported high grade copper, gold and silver assays indicating a potential strike length of the target zone in excess of 3km’s (Refer to Figure 3).

Multiple New Lithium (LCT) Pegmatite Targets Confirmed
HIGHLIGHTS
- Independent geological experts RSC consultants have identified four priority target areas for Lithium-Caesium-Tantalum (“LCT”) Pegmatites within the Company’s Critical Elements Projects, located in the centre of the rapidly developing Gascoyne “Battery Metals” Province, WA
- Each of the target areas are associated with confirmed fertile parental granites of the Thirty Three and Durlacher Supersuites and contain the same metasedimentary sequences which host Red Dirt Metals (ASX: RDT) Yinnetharra Lithium Project, less than 10 km’s to the NE of Reach Resources’ tenure
- All of the targets are defined by favourable geology, multi-element pathfinder geochemistry and the presence of mapped Geological Society of Western Australia (GSWA) Tin, Tantalum and Lithium pegmatites
- A helicopter supported field reconnaissance program has been initiated to assess the priority areas in more detail
- Drilling of priority targets is scheduled to commence in CY Q3/4 2023 once all regulatory approvals are received
CEO Jeremy Bower commented:
“RSC’s independent expert analysis confirms our belief that our landholding in the Gascoyne has the potential to host significant battery metal deposits.
Phase 1 of the assessment focused on the lithium potential at our Critical Elements Projects and has not only cemented Morrissey Hill as our primary lithium target but importantly has identified three new lithium target areas. Each of the areas are defined by the presence of a highly fertile parent granite and supported by key multi-element geochemistry including lithium, caesium, tantalum, tin and rubidium which are all well documented associations of lithium bearing “rare metal” LCT pegmatite mineral systems.
This is an exciting time for the Company and our shareholders, and we look forward to delivering updates to the market over the coming months. The Future is within Reach”.
Phase 1 of the assessment focused on the lithium potential of the Company’s Critical Elements Projects which includes the newly acquired Morrissey Hill and Camel Hill projects as well as the Wabli Creek project (Figure 1).
Figure 1: Critical Elements Projects
The assessment included a review of relevant deposit models and mineralisation styles of interest, regional and local geology, local mineral systems, academic papers, open file company and government reports and all available geochemical, geophysical and remote-sensed data sets.
